Sina that was a pretty simplified description. If you want to get technical you 
can have more than one class as long as they are internal classes.

Please put each class in its own .java file. You can only have one class per 
file. The class name must match both in case and contents to the name provided 
to the filename.

 

Take care,

I think you can only have a single public class per file.

Dear Brandon,

 

Whether or not you realize it, you are way ahead of yourself in Java for being 
a novice.  I took a Java course last semester, and interfaces were not 
introduced.  Interfaces will be introduced and used in the second course.  
Below, I will attempt to answer your questions as well as provide an additional 
resource for learning Java so you are not getting ahead of yourself.

 

The HelloWorldApp had everything in it. It didn't need a interface, why do we 
need to make a separate interface for all our other classes?

You do not need to make an interface for each class.  This is where you skimmed 
too far ahead in the tutorial.

Why do we have to create an interface when the class already has the same code 
in it?

Interfaces are for designing larger, complex applications.  Please do not worry 
about them at this stage.

Do you save all classes as a .java file then use javac to compile it into a 
.class file?

Yes, all classes can be in a single .java file, or you can have a .java file 
for each class.

What do you save interfaces as?

Interfaces would also reside in .java files. 

 

Personally, I find a good textbook better for learning the programming thought 
process than an online tutorial.  Tutorials are great for explaining language 
features, but leave out a lot of information for the programming thought 
process.  A Java textbook I really like is called Introduction to Programming 
Using Java and located at http://math.hws.edu/javanotes/.  This textbook is 
free and it does not matter whether or not you have had programming experience. 
 Bruce Eckel’s Thinking in Java assumes previous experience with the C 
language. 

 

Finally, to address the whole group, I agree with those who said working in an 
environment such as an IDE is probably easier for a novice than the command 
line.  This will probably always be an on-going debate, because there are pros 
and cons to both.  However, all I am going to add is that regardless of the 
environment, you do not need to know everything about that environment to get 
started writing basic programs.  Now, I personally like Sodbeans because it is 
great for catching compiler errors in the text editor and announcing them 
before you go through the trouble of trying to build the application.  This is 
an excellent benefit!  Now, Sodbeans is based on Netbeans which is a huge 
environment, but don’t worry about learning Netbeans.  Focus on learning the 
basics that will get you started writing simple applications.  I would be happy 
to help you get started.  In fact, a good mentor is often the best a novice 
programmer can have, which is maybe why mentors are hard to find.  If you would 
like to contact me, I use Skype.  That would be the easiest.  My Skype username 
is foxwarrior09. 

 

Sincerely, 

Mike

Hello, 

I finally had time to go past the HelloWorldApp in the tutorial. :D 

Now I'm trying to create my own classes then run them through my interface... 

But I'm a little confused: 

 

The HelloWorldApp had everything in it. It didn't need a interface, why do we 
need to make a separate interface for all our other classes? 

 

Why do we have to create an interface when the class already has the same code 
in it? 

 

Do you save all classes as a .java file then use javac to compile it into a 
.class file? 

 

What do you save interfaces as? 

 

I created a class for my heater: 

 

/** creates the class for heater which has temperature, speed and onOff
*/
class Heater } 

 

int temperature = 0
int speed = 0
int turned = on 

 

voide changeTemprature(int newValue) {
temperature = newValue;
} 

 

voide speedUp(int increment) {
Speed = speed + increment;
} 

 

voide slowDown(int decrement) {
Speed = speed - decrement;
} 

 

voide turnOn() {
Turned = on;
} 

 

voide turnOff() {
Turned = off;
} 

 

voide printStates() }
System.out.println("temprature:"+temprature+" speed:"+speed+" turned:"+turned);
}
}

Where do I put the lines like: 

public static void main(String[] args) 

and 

System.out.println 

? 

Also do I have the right idea with the word after void is the word I type to 
turnOn the heater? 

And the word after (int is the word that could be what ever I want it to be, it 
just needs to be the same below?) 

Example: 

 

voide slowDown(int pizza) {
Speed = speed - pizza;
} 

? 

 

If you have any question, the interface for the heater is: 

 

interface Heater } 

 

voide changeTemprature(int newValue); 

 

voide speedUp(int increment); 

 

voide slowDown(int decrement); 

 

voide turnOn(); 

 

voide turnOff();
}

Sorry, I didn't see answers to these questions in the tutorials and I need to 
know this to do anything! Description: Sad smile emoticon

Thank you,

That’s not learning a language Ken, that’s learning an SDK, which implies one 
already knows how to use the language. 

 

I think you should start off with text as well, so that six months later you 
aren’t asking basic questions like why doesn’t this class run, because you 
never had to put a mian method in it since Eclipse always did that for you, 
etc. etc. 

 

Of course, that implies that you actually want to learn the fundamentals of the 
language, and not just code. 

 

Take care, 

Sina

I have to disagree with this.  There is nothing like using eclipse when you’re 
learning a language.  Let’s say you are in Android and need to make an 
Application.  Ok so you start it up and there is an Activity class.  You’re in 
your text editor what do you do? 

 

You go out on line or into a document and try to read up on all the possible 
functions you can run in an activity.   Not bad but why not make it quicker. 

 

Just arrow to your myactivity and use the source menu and go down and select 
override members.  Then you can arrow through the list of things you have that 
you can do in that class.  You check a few and tab down and hit ok.  Now you 
have 6 stub functions that work perfect.  You then go down to the keydown 
function that you just added  and arrow over keyEvent and select help it tells 
you all the functions  

 

Eclipse and Visual studio are  not just environments but they are  great 
learning tools.  Not to mention learning the environment now with an easy 
program will  speed up both development of a harder program but it also teaches 
you how to download other peoples projects and get them running.  

 

Heck for that matter if you don’t use eclipse you have to learn another way to 
compile your project.  Which normally means you start compiling at the command 
line with javac.  That sounds easy but how many of you have tried this and ran 
into the java path problems.  That is not something you want to get a new user 
into right away.  Then if you want to get real bold and use ant as a new 
programmer you better have a lot of antacid. 

 

So I guess in short I just wanted to say sure Eclipse is a big pig but the 
gains for a new coder is pretty high if you learn to use it.  Now if you’re on 
a Mac sorry to hear it while I like Mac I have not been impressed with the 
amount of work I had to go through to get Eclipse set up.  I use it on both Mac 
and Windows but I will tell you there is nothing like Eclipse and Jaws 12.  I 
use no scripts and do just fine.

Hi Brandon, 

This is my opinion, so take with a grain of salt. Right at the beginning with 
Java, I feel that you should use a text editor. Personally, I prefer EdSharp, 
but there  are lots of good ones. Learn to use the command line tools that come 
with the Java Development Kit. After you have written some programs, and you 
know what's going on with basic Java, start to use something like Eclipse or 
Net Beans. I have no experience with SodBeans, but I understand that that 
package for NetBeans is making a big difference in NetBeans accessibility. So 
scrap fancy editors for now.

Thanks and I started reading those, the only problem is I use Eclipse and these 
talk about the Netbeans IDE which I think it is inaccessible. 

My big question is: What are all the differences in the different things you 
can create with the new menu in Eclipse? There are like projects, classes, Java 
projects and all kinds of other things that aren't really talked about with 
Java. 

Thanks,

Hi, 

I think that, as with many things, this is one of those things that can be 
different, depending on the learning style and knowledge of the person. 

 

Speaking just for myself, I get more out of tutorial style books, when I'm 
learning a language. I tend to freeze up at reference type material that is 
full of code and short on words, but that's my taste. 

 

According to me, you will probably do well with the nutshell books, if you 
already know lots of programming concepts and want to see how certain things 
are done in Java. On the other hand, you may do better if you have little 
programming experience by looking at the Java Tutorial, which takes things a 
concept at a time and explains them with lots of words and examples. You can 
see that at http://download.oracle.com/javase/tutorial/reallybigindex.html. 

 

Thanks.

I would recommend if you have a subscription to bookshare.org, that you 
download a copy of "Java in a Nutshell".  It is a nice summary of features with 
some examples.  I was going to read "Thinking in Java, 4th edition", which I 
forked $25 for online, but got a package that I cann't display on my system.  I 
have been unable to read more than the preface, and most the time, the html 
just freezes things.  So I'm pitching it.  A shame as it sounds like a useful 
guide to using java the way it is meant to be used. 

  

Online there are also common tasks implemented in java, which you can find in 
http://commons.apache.org/ 

Good luck and happy hacking.

Hello Brandon, 

 

Do you have any form of IM or perhaps skype? I would like to help you but it's 
easier for me to recommend something if i know a bit more about your 
background.

Hello, 

I'm new to programming, (I have just made it past "Hello World") and am looking 
for some guides. 

I would like to learn Java, but I'm not quite sure where to start. I downloaded 
the 500 or so documents from the "Java Documentation" at: 

http://www.nonvisualdevelopment.org/node/20 

as well as reading all the tutorials on Eclipse and Java. 

I've installed the SDK 1.6 and Eclipse, is there anything else I need? I see 
there are Jaws scripts for Eclipse, where do I insert those? 

I arrowed through the 500 documents dealing with Java and found: 

Java Tutorial 3rd Edition, a short course on the basics 

but I see it was written in 2001 and only deals with Java 1.3 and Windows 2000 
and before. Is this something I should read? What books best describe the 
language in an exciting and useful format? I'm wanting to eventually program 
for Android, but I think that is stepping a little ahead of myself. 

Where do I start? 

Thanks,
